DRIVER ASSISTANCE SYSTEM COMPRISING A CENTRAL UNIT AND AT LEAST ONE CAMERA, AND CORRESPONDING IMAGE DATA TRANSMISSION METHOD
Driver assistance system comprising a control unit, at least one camera configured to transmit image data to the control unit, a first embedded secure element connected to the camera and a second embedded secure element connected to the control unit, wherein the first embedded secure element is configured jointly with the second embedded secure element to perform an authentication of the image data during a transmission of the image data from the camera to the control unit.
1 . A driver assistance system comprising a control unit, at least one camera configured to transmit image data to the control unit, a first embedded secure element connected to the camera and a second embedded secure element connected to the control unit, wherein the first embedded secure element is configured jointly with the second embedded secure element to perform an authentication of the image data during a transmission of the image data from the camera to the control unit.
2 . The system according to claim 1 , wherein the first embedded secure element and the second embedded secure element are configured to authenticate the image data with one-time use secure data.
3 . The system according to claim 2 , wherein the first embedded secure element and the second embedded secure element each comprise a secure memory configured to store a seed key, and generation means configured to generate the one-time use secure data from the seed key.
4 . The system according to claim 2 , wherein the first embedded secure element is configured to mark the image data with the one-time use secure data and the second embedded secure element is configured to verify the image data marked with the one-time use secure data.
5 . The system according to claim 3 , wherein the first embedded secure element is configured to mark the image data with the one-time use secure data and the second embedded secure element is configured to verify the image data marked with the one-time use secure data.
6 . The system according to claim 4 , wherein the first embedded secure element and the second secure embedded element are configured to authenticate the image data by performing an exclusive OR Boolean operation between the image data and the one-time use secure data.
7 . The system according to claim 2 , wherein the first embedded secure element is configured to encrypt the image data by using the one-time use secure data and the second embedded secure element is configured to decrypt the image data encrypted by using the one-time use secure data.
8 . The system according to claim 3 , wherein the first embedded secure element is configured to encrypt the image data by using the one-time use secure data and the second embedded secure element is configured to decrypt the image data encrypted by using the one-time use secure data.
9 . The system according to claim 7 , wherein the first embedded secure element is configured to encrypt at least one portion of the image data of an image selected from a set of images of a video stream.
10 . The system according to claim 8 , wherein the first embedded secure element is configured to encrypt at least one portion of the image data of an image selected from a set of images of a video stream.
11 . A method for transmitting image data from at least one camera to a control unit within a driver assistance system comprising an authentication of the image data with one-time use secure data by a first embedded secure element connected to the camera and a second embedded secure element connected to the control unit.
12 . The method according to claim 11 , wherein the authentication of image data is performed with one-time use secure data.
13 . The method according to claim 12 , comprising storing a seed key in a secure memory of the first embedded secure element and of the second embedded secure element and generating secure data from the seed key.
14 . The method according to claim 12 , wherein the authentication of the image data comprises marking the image data with the one-time use secure data and verifying the image data marked with the one-time use secure data.
15 . The method according to claim 13 , wherein the authentication of the image data comprises marking the image data with the one-time use secure data and verifying the image data marked with the one-time use secure data.
16 . The method according to claim 13 , wherein the authentication comprises an exclusive OR Boolean operation between the image data and the one-time use secure data.
17 . The method according to claim 12 , wherein the authentication comprises encrypting the image data with the one-time use secure data and decrypting the image data encrypted with the one-time use secure data.
18 . The method according to claim 13 , wherein the authentication comprises encrypting the image data with the one-time use secure data and decrypting the image data encrypted with the one-time use secure data.
19 . The method according to claim 17 , wherein encryption is performed on at least one portion of the image data of an image selected from a set of images of a video stream.
20 . The method according to claim 18 , wherein encryption is performed on at least one portion of the image data of an image selected from a set of images of a video stream.
